*	[test] Fix use of 'sort -b' in SimpleLoopUnswitch on NetBSD	Michal Gorny	2018-12-02	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \|	Add '-k 1' to 'sort -b' calls in SimpleLoopUnswitch tests, as required for sort implementation on NetBSD. The '-b' modifier is ineffective if specified without any key. Per the manpage: Note that the -b option has no effect unless key fields are specified.

*	[SimpleLoopUnswitch] adding cost multiplier to cap exponential unswitch with	Fedor Sergeev	2018-11-16	1	-0/+118
	We need to control exponential behavior of loop-unswitch so we do not get run-away compilation. Suggested solution is to introduce a multiplier for an unswitch cost that makes cost prohibitive as soon as there are too many candidates and too many sibling loops (meaning we have already started duplicating loops by unswitching). It does solve the currently known problem with compile-time degradation (PR 39544). Tests are built on top of a recently implemented CHECK-COUNT-<num> FileCheck directives.
